COFFEE-ROASTER.

Specification of Letters Patent.

Patented July 20, 1909.

Application filed. June 12, 1908. Serial No. 438,216.

To all whom it may concern:

Be itknown that I, NOAH T. GoLnY, a citizen. of the United States,residing at vVilson, in the county of Vilson, State of North Carolina,have invented certain new and useful Improvements in Coffee-Roasters;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

The invention relates to roasting machines and more particularly to theclass of coffee roasters.

The primary objectof theinvention is the provision of a roaster having arotatable cylinder for receiving coffee and the like to be roasted,driving mechanism for rotating the cylinder and having a governor, aheating compartment or chamber and a casing inclosing the rotatablecylinder and a portion of the heating compartment, the said casing beingremovable.

Another object of the invention isthe provision of a roaster for coffeeand the like which is simple in construction, eflicient in operation andinexpensive in the manufacture.

With these and other objects in view the invention consists in theconstruction, combination and arrangement of parts as will behereinafter more fully described and as illustrated in the accompanyingdrawings which disclose the preferred form of embodiment of theinvention.

be made such as come properly within the scope of the claims hereuntoappended, without departing from the spirit of the invention.

In the drawings :F igure 1 is a front view of the invention. Fig. 2 is aview of one end of the same, with the casing partly broken away. Fig. 3is a view of the other end. Fig. 4c is a top plan view of the roasterwith the casing removed. Fig. 5 is a longitudinal sectional view of thedrum or cylinder detached. Fig. 6 is a transverse vertical sectionalView through the removable casing and drum.

Similar reference characters indicate corresponding parts throughout theseveral views in the drawings.

In the drawings, the numeral 10 designates a base or bed plate of themachine having an upright or standard 11 terminating However, changes,variations and modifications may able bearing cars 12 for detachablyreceiving a hollow journal 13 secured centrally of a removable end cover1 1 which frictionally engages a cylindrical mouth opening 15 at one endof a drum or cylinder 16 which latter is adapted to receive coffee andthe like to be roasted. The opposite closed end 17 of the cylinder has acentrally projecting journal 18 detachablymounted in a bearing recess 19of a short standard 20 secured to the motor or clock frame hereinafterdescribed.

Mounted upon the base or bed plate 10 near the opposite end thereof arevertical standards 21 supporting a motor frame 22 arranged at one sideof the drum and which frame includes spaced side plates 23 arranged inparallel relation to each other and united by transversely disposedconnecting end rods 24-. Journaled in the side plates 23 is a windingshaft 25 0f a main spring 26 controlling a driving gear 27 in mesh witha pinion 28 having a gear wheel 29 fixed to a shaft30 journaled in themotor frame and which gear wheel 29 enmeshes with a pinion 31 fixed to adriving shaft 82 journaled in the motor frame and projecting through andbeyond the standard 20 and having mounted thereon at its free end apinion 33 which latter mesheswith a cog wheel 34 fixed to the journal 18of the drum or cylinder whereby the latter is adapted to be rotatedthrough the medium of the gearing by the main spring controlling thedrive gear. Upon the drive shaft 30 is a gear wheel 35 enmesh with apinion 36 on a shaft 37 journaled in the motor frame and which lattershaft has fixed thereto a wheel 38 provided with peripheral side teeth39 enmesh with a pinion 40 fixed to a vertically disposed governor shaft41 having its upper end engaging a bearing bracket 42 secured to themotor frame and the opposite end of said governor shaft having itsbearing in a bearing block 43 secured to the base plate 10 of themachine. The governor shaft 4C1 carries a weighted ball governor 4C4controlling a slidable sleeve t5 on the governor shaft and having a disk46' engaging a brake-shoe 47 carried by a yieldable arm 48 mounted upona vertical standard 49 on the base plate of the machine.

Immediately below the rotatable drum or cylinder 16 isa semi-circularplate 50 forming the top of a lamp space 51 and which plate is mountedupon vertical end walls 52 at its upper end in oppositely disposedyield- 1 secured to the base or bed plate. Upon the said base or bedplate 10 between the end walls 52 is positioned a burner 53 which may beof any suitable construction.

To inclose the drum of cylinder 16 thereis provided a removable casing54 having a curved top wall 55 extended downwardly to form a rearclosing wall 56 united to end walls 57 the latter having centralvertically disposed open slots 58 for receiving the journals of the drumor cylinder when the casing is brought to a position to inclose the saiddrum. The lower front portion of the casing is open as at 59 to permitthe introduction and withdrawal of the burner. It is obvious that due tothe formation of the removable casing 5a by having a curved top wallpermits the heat from the burner to pass around the rotatable cylinderor drum 16 and out through the open front 59 of said casing. Thesemi-circular plate 50 directs the heat from the burner to the top ofthe casing. The hollow journal 13 forms an exhaust port or outlet incommunication with the rotary cylinder or drum to permit excessive heatto escape therefrom.

lVhat is claimed is 1. A roaster of the class described comprising abase, a standard mounted at one end of said base and terminating inyieldable bearing ears, a motor frame mounted at the other end of thebase, a standard formed on said motor frame and having a bearing recess,a rotatable drum having journals at opposite ends thereof mounted in thebearing ears and recess respectively, motor mechanism supported by saidmotor frame and adapted to rotate said drum, a semi-circular platehaving spaced vertical side walls arranged immediately below the drum toform a lamp space, a removable lamp supported upon the base within saidlamp space, and a casing inclosing saiddrum and adapted to form a spacebetween the latter and said casing.

2. A roaster of the class described comprising a base, standards risingfrom said base, one of said standards having yieldable bearing ears andthe other containing a bearing recess, a rotatable drum having journalsengaging the recess and yieldable bearing ears, one of said journalscontaining an exhaust passage leading from the interior of the drum tothe atmosphere, and spring actuated motor mechanism having connectionwith the drum to rotate the same.

3. In a roasting machine, a base, standards rising from said base,yieldable bearing ears formed on one of said standards, the otherstandard being provided with a bearing recess, a rotatable drum havingjournals engaging the bearing ears and recess of the standards, one ofsaid journals being provided with an exhaust port, motor mechanismsupported by said base and having gear connection with the drum torotate the same, and a removable casing for entirely inclosing the drum.V v

at. In a roasting machine, a base, a stand; ard mounted at one end ofthe said base and terminating in yieldable bearing ears, a motor framemounted upon the other end of the base, a standard secured to said motorframe and having a bearing recess, a rotatable drum having an open end,a detachable cover for closing the open end of the drum, a journalprojecting from the closed end of the drum and detachably mounted in thebearing recess in the standard on the motor frame, a hollow journalfixed to the detachable 7 cover and detachably engaging the yieldablebearing ears of the other standard, said hollow journal forming anexhaust port for the drum, a burner arranged below the said drum, aremovable casing for entirely inclosing the drum and spring motor meclranism for rotating the drum.

In testimony whereof, I affix my signature, in presence of twowitnesses.
